Broncos quarterback Mark Sanchez is one of several pro athletes to lose millions of dollars in a Ponzi-like investment scheme, federal investigators said Tuesday.

HOUSTON — Several professional athletes, including Denver Broncos quarterback Mark Sanchez, San Francisco Giants pitcher Jake Peavy and retired Houston Astros pitcher Roy Oswalt, were cheated out of more than $30 million by an investment adviser in a Ponzi-like scheme, federal investigators said Tuesday.

In a lawsuit filed last month in Dallas federal court, the Securities and Exchange Commission alleges that Ash Narayan told his clients he was pursuing a low-risk investment strategy for their money but actually put more than $33 million of it into an Illinois-based online sports and entertainment ticket business, The Ticket Reserve, that had lost money for the last four years. It also says he didn’t tell them that The Ticket Reserve paid him nearly $2 million in finder’s fees for directing their money to the company.

“Narayan exploited athletes and other clients who trusted him to manage their finances. He fraudulently funneled their savings into a money-losing business and his own pocket,” Shamoil T. Shipchandler, director of the SEC’s Fort Worth regional office, said in a statement.

The SEC’s lawsuit alleges that Narayan, The Ticket Reserve, the ticket company’s CEO, Richard Harmon, and its chief operating officer, John Kaptrosky, violated antifraud provisions of federal securities laws and a related SEC antifraud rule, and accuses Narayan of violating the antifraud provisions of the Investment Advisers Act of 1940.

The SEC said Tuesday that it obtained a court order freezing the assets of Narayan, Harmon, and Kaptrosky. A receiver has also been appointed to manage the ticket business. No criminal charges have been filed.

“Mr. Narayan has always sought to act in his clients’ best interests. Accordingly, he will continue to work with the SEC to ensure that this matter is resolved in the most favorable manner for those clients,” Howard M. Privette, Narayan’s attorney, said in an email.

Court records did not list attorneys for Harmon and Kaptrosky. They did not immediately return a phone message seeking comment on the lawsuit left with The Ticket Reserve.

Narayan worked out of Irvine for a Dallas-based financial firm, RGT Wealth Advisors, from 1997 until earlier this year. In a statement, RGT said it fired Narayan after discovering what he had done.

“These actions did not conform to RGT’s high standards of client service and our core values of integrity and professionalism,” RGT said. “We are outraged by this conduct, and are working hard to try to recoup invested funds for the clients involved.”

According to court documents, Narayan directed more than $30.4 million into the ticket business from three current and former athletes: $15.1 million from Peavy, nearly $7.8 million from Sanchez and nearly $7.6 million from Oswalt.

In statements filed as part of the lawsuit, both Peavy and Sanchez said they believe Narayan forged their signatures to transfer money from their accounts to the business.

Peavy said he had been working to set aside $20 million for after his playing days were over.

“Between 2011 and 2016, Narayan invested approximately $15 million of my funds in (the ticket business) without my authorization. This represents the vast majority of the personal funds that Narayan managed for me. … To date, I have yet to receive a return on any of my funds used to invest in” the ticket business, Peavy said.

Before the Giants’ game Tuesday in Pittsburgh, Peavy said he can’t speak publicly on the SEC investigation.

“We’re working through it best we can. Just have got to stay focused on this team and doing my job. … There’s always outside distractions in what we do. This obviously has been one,” he said.

All three athletes said they hired Narayan in part because he represented himself as a devout Christian involved in charitable causes and claimed to be a certified public accountant. The SEC says Narayan has never been a CPA.

In his statement, Sanchez, who attended Mission Viejo High and USC, said he had agreed to make only a $100,000 investment in the online ticket company and “because it is such a risky investment, I would not have knowingly invested additional funds in (the business) — much less committed millions of dollars to that company.”
